Why This Document

Overseas engineers and procurement managers evaluating a custom-cut bar/stretched LCD module usually need the same set of answers before they can approve a project internally: is the cut geometrically feasible, will it survive the field, and what will it cost and when will it arrive. This brief answers those questions directly, organized around the three stages of a typical technical evaluation.

1. Cutting Process & Feasibility Assessment

Cutting method selectionFor narrow-bezel and non-standard aspect-ratio bar displays like the P280IVN01.1, HITULCD selects the cutting method based on the required tolerance and panel construction:

Our engineering team recommends the method after reviewing your target dimension, tolerance class, and cut-line location relative to the panel's active area — we do not default to one method for all requests.

Trace and active-area clearanceBefore confirming feasibility, we map the intended cut line against the panel's Gate/Source driver traces and TFT array boundary to confirm no interference with signal routing. This is standard practice for all stretched-bar customizations, not an extra step.

Drawings/data required from you for a feasibility check:

• Target outline dimension (with tolerance class, e.g. ±0.3 mm or ±0.1 mm)

• Mounting/cutout drawing (DXF or DWG preferred) showing the exact cut boundary relative to the panel's reference corner

• Required active area (viewable image size) and its position within the cut boundary

• Base panel size/model if you are cutting down an existing standard panel, or confirmation that a new base panel should be sourced

Edge finishing standardPost-cut edges are ground and polished to remove chipping and micro-cracks, then inspected under magnification against an internal edge-quality standard (no visible chip >0.1 mm, no crack propagation into the active area) before moving to sealing.

2. Reliability & Edge Sealing Assurance

Sealing processAfter cutting, the exposed glass edge is treated with a secondary edge-sealing process — typically UV-cure resin dispensing along the cut edge, with the dispensing path and cure profile adjusted per panel thickness — to restore moisture and liquid-crystal leakage protection at the new edge.

Reliability testingCut-and-sealed modules go through the same reliability program as our standard panels, scoped to industrial or consumer grade depending on your application:

• Temperature/humidity: 85°C/85%RH endurance ("double 85") test

• Thermal shock: high/low temperature cycling

• Mechanical: structural drop test

• Operating range for this model: -20°C to 60°C

We can share test summary data (pass/fail criteria and duration) from comparable stretched-bar cutting programs on request — please specify whether your application requires consumer-grade or industrial-grade qualification, since the test plan and acceptance criteria differ.

Optical performance at the cut edgeThe sealed edge zone is inspected for light leakage and color shift (Mura) under dark-room conditions. A well-controlled cut-and-seal process should show no visible Mura within the specified active area; any deviation is a rejection criterion at final QC, not something passed on to the customer.

3. Cost, Yield & Lead Time

NRE and samplingNon-recurring engineering costs for a custom cut project depend on tolerance class, cut geometry complexity, and whether new tooling/fixtures are required — this is quoted per drawing, not as a flat fee. As a general guide, first-article samples (typically 20 pcs) are available in 2–4 weeks from drawing confirmation; standard (non-cut) products ship in 2–3 weeks, custom projects in 4–6 weeks.

Volume expectations

• MOQ: 1 unit for standard specifications; custom cutting, brightness, or bezel changes may adjust MOQ, confirmed at quotation

• Production yield: varies with tolerance class and cut geometry — tighter tolerances and complex profiles run lower yield than simple straight-line cuts at standard tolerance. We provide a yield estimate as part of the formal quotation once your drawing and tolerance are confirmed

• Capacity: 12,000+ units/month across our production line, supporting prototype, small-batch, and volume programs

Commercial terms

• Incoterms: EXW / FOB / CIF

• Payment: T/T (standard for bulk), L/C (large volume), PayPal (samples), O/A (long-term partners)

• Warranty: 12 months with ongoing engineering support

Next Step

To move to a formal feasibility review, please send:

1. Cut boundary drawing (DXF/DWG) with tolerance class

2. Target quantity for sampling and for annual volume

3. Application environment (indoor/outdoor, expected duty cycle) so we can confirm the correct reliability test tier

Our engineering team will return a feasibility confirmation, sealing/testing plan, and formal NRE + sample lead-time quote based on the above.
